Hey,
my rfcomm.conf was commented out, so I edited it like yours, but it is still not working.
It looks like this:
rfcomm0 {
# Automatically bind the device at startup
bind yes;
# Bluetooth address of the device
device 00:12:11:12:06:48;
# RFCOMM channel for the connection
channel 1;
# Description of the connection
comment "arduino";
}
